with identical structures—that is, identical diameters and chiralities—display different emission energies, although each individual emission line does match transitions observed in ensembleaveraged spectra. The researchers used low-energy Raman scattering attributed to the nanotube’s radial breathing mode to verify that the source of the fluorescence was individual nanotubes. The researchers attribute the heterogeneous emission properties obtained from SWNTs with identical diameter and chirality values to localized defects and perturbations. For moderate excitation energies (
